Be it known that we, ETHAN R. CHENEY, of Boston, in the county of Suffolk and, State of Massachusetts, and JOHN J. EMERY, of Owls Head, in the county of Knox and State of Maine, have invented certain Improvements in Chain Stoppers or Holders, of which the following is a specification.

This invention is an improvement upon that l described in the patent of J. J. Emery, issued Septe1nber21, 1869, and re-issued to himself it is forced by the recoil of the springs, and to the arrangement of supporting stay-rods for the guides and standards, all as more fully set forth below.

Whenever the strain is relaXed, the springs recoil, and if the relaxation is sudden the part A will be thrown backward by the recoil somewhat violently.

To overcome the shock occasioned by the part A being thrown in this manner against the standard G, We have provided between it and the standard G the elastic cushion H, which relieves the. shock and prevents danger of breakage.
